Very nice playing! A lot better than I can do, certainly!
However, I don't know if it's because you were trying some specific motives, but I noticed that your phrases didn't connect between verses, and I think that that step is the next thing you could do to get your playing to the next level.
An exercise that my teacher told me to do is yo play through the whole song using only whole notes and half notes (whole when the chord is 1 bar, half when there are 2 chords per bar). Then in quarter, eighths....BUT, using only chord tones. If you can play chord tones non-stop in 8th or 16th notes through the whole song, there's no theorical limit to the lenght of your phrases (now they are a little predictable in that area, most of the time they will finish every 4 bars).
Hope this helps, and again great playing!
